When Attorney General Eric Holder recently testified before the Senate Judiciary Committee about his role in the Fast and Furious operation, where 2,000 rifles were deliberately “walked” from the United States into Mexico, his answers at times seemed incredible and stretched the limits of believability.

A few months earlier, on May the third, Holder had testified before the House that he had only recently learned of the deadly and disastrous operation.

But a series of memos was uncovered by CBS News last October showing that during 2010, Holder had received at least five different notices concerning Fast and Furious from Michael Walther, the director of the National Drug Intelligence Center. He also received another memo from Assistant Attorney General (and long-time associate) Lanny Breuer.

But at the recent hearing, Holder stated three times that he had learned of Fast and Furious only earlier this year, after the murder of Border Patrol Agent Brian Terry in Arizona. Five times Holder testified that he never saw any of the damning memos.
